Thank you very much sir , you have managed to rescue me from deep water of Atlantic Ocean , the major mistake I making was calling the code wrongly like you pointed out below:
Call jstCheckTableLinks_Full() exactly this is where the problem was.
Now I have also created a button to facilitate the change of linked BE to another just in case need arises in future as follow:
Call jstCheckTableLinks_Prompt()
Once again thank you so much
Regards
Chris
